Saint Helena (Latin: Flavia Iulia Helena Augusta) also known as Saint Helen, Helena Augusta or Helena of Constantinople (ca. 246/50  18 August 330) was the consort of Emperor Constantius, and the mother of Emperor Constantine I. She is traditionally credited with finding the relics of the True Cross, with which she is invariably represented in Christian iconography. Constantine the Great (Latin: Flavius Valerius Aurelius Constantinus Augustus; c. 27 February 272[2]  22 May 337), also known as Constantine I or Saint Constantine, was Roman Emperor from 306 to 337. Well known for being the first Roman emperor to convert to Christianity, along with co-Emperor Licinius, Constantine issued the Edict of Milan in 313, which proclaimed religious tolerance of all religions throughout the empire.
